AUBURN, Alabama -- Kiehl Frazier could move back to offense full time next week.

Or he might continue to split time with Auburn's offense and defense.

The junior moved from quarterback to safety and even changed jersey numbers to solidify the change in August, but has since played several snaps as Auburn's Wildcat quarterback, especially in short-yardage situations, over the last two weeks.

"We're still working through that," coach Gus Malzahn said Monday. "Maybe at the end of the week we'll define that a little more clearly."

Frazier has two carries for only three yards. He rushed for a 1-yard loss in the 35-21 loss at LSU, but his hand-off to Corey Grant inside the 10-yard line picked up 7 yards and set up Tre Mason's 2-yard touchdown run late in the third quarter.

Frazier's role in the Wildcat package is similar to the one Malzahn utilized during the former five-star prospect's freshman season, when he rushed for 327 yards and three touchdowns on 76 carries in 2011.

He has yet to break through -- or record a first down -- as the Wildcat quarterback this season.

Frazier (6-2, 224) provides Auburn a bigger physical threat on run plays. It also keeps starting quarterback Nick Marshall, a smaller and faster runner, from taking a big hit in the middle of the field in short yardage situations.

"We know what we're getting with Kiehl," Malzahn said. "We've got information, he was very successful as a freshman doing some things and he'll have a chance to help us."

Offensive coordinator Rhett Lashlee says Frazier is a "jack-of-all-trades" for the Tigers. His role with the offense and defense will be determined week by week, he said.

It's possible Frazier could throw a pass or two this season as well.

"There's certain situations where you maybe don't want your quarterback taking as many hits downhill and that definitely provides another option," Lashlee said. "But hey, he's also a guy that started at quarterback last year, so he's not one-dimensional either."

Frazier was benched after five starts last season. He completed only 53.4 percent of his passes for 753 yards and two touchdowns with eight interceptions.

Auburn has used three different players in the Wildcat package this season: Frazier, backup quarterback Jonathan Wallace and running back Cameron Artis-Payne. Wallace (two carries, 7 yards) led the Tigers on a touchdown drive late in the fourth quarter against Arkansas State in Week 2.

"There are some plays here or there that we feel those guys fit, take something off of Nick," said Lashlee, "and if it fits, we'll do it. If it doesn't, we won't. We won't force that issue."

Frazier's only action this season outside of his role on offense arrived late in Week 2 on kickoff coverage and at safety during Arkansas State's final possession.
